Crisis Situations

In extreme (crisis) situations, tasks arise, requiring an answer to the question of the effectiveness of decisions made. When using radio technicians of special purpose, the results depend on both the ability of the equipment and its condition and from the service personnel. At the same time, it is necessary to take into account the presence of targeted interfering factors. The paper proposed a method for evaluating the operation of radio equipment for special purpose in extreme (crisis) situations, a distinguishing feature of which is to account for the mutual influence of the components of the system. The evolution of the basic component of operation is proposed to approximate polynomial dependence using a fuzzy logic apparatus when making resulting solutions.

The article discusses the concept of a natural recreational system (NRS) as a set of interconnected areas of inaccessibility, tourists, regulatory authorities and service personnel. For the development of tourism in natural areas, it is necessary to study the connections between these subsystems, which determined the purpose of the study – to structure the NRS, for which it is necessary: to study the subsystem of tourists, engaged in various types of nature-oriented tourism; examine the subsystems of regulatory bodies and service personnel and determine their functions; to analyze the mutual influence of four NRS subsystems. The first subsystem includes areas of inaccessibility, on the territory of which different types of travel are carried out. The second subsystem consists of tourists traveling in areals of inaccessibility, where they are engaged in nature-oriented, active, sports, ecological and extreme tourism, as well as recreation. The third subsystem consists of bodies that control tourist processes in areas of inaccessibility. This includes the Ministry of Emergencies, which regulates the activities of search and rescue services responsible for search and rescue on the territory of Russia. Route qualification commissions are the controlling body of sports tourism. Insurance companies can interact with tourists involved in all types of nature tourism. The fourth subsystem is optional; it consists of service personnel and, in some cases, tourist infrastructure. At the same time, there are direct and feedback links between the subsystem of tourists and the subsystems of regulatory bodies and service personnel. There are only direct links between the tourist subsystem and areals of inaccessibility.

The study of the factors that form the threats to the violation of the properties of the availability and integrity of aeromonitoring video information in the system of prevention and elimination of crisis situations. The direction of increasing the availability of video information based on the use of compression technology for encoding video data has been substantiated. It is shown that to eliminate the drawback associated with lowering the lower boundary of the differential polyadic space, it is necessary for the perforation technology to additionally take into account the binary mask of burst elements of the upper and lower levels. The main conceptual components of the image compression method to increase the availability of video information, based on the coding of composite numbers with a mask in a differential perforated polyadic space, have been developed. The main results of a comparative assessment of the basic component of information availability in aeromonitoring systems are presented.

13Co2 Enrichment

Abstract.A new method was developed for continuous isotopic estimation of human whole body CO2 rate of appearance (Ra) during non-steady state exercise. The technique consisted of a breath-by-breath measurement of 13CO2 enrichment (E) and a real-time fuzzy logic feedback system which controlled NaH13CO3 infusion rate to achieve an isotopic steady state. Ra was estimated from the isotope infusion rate and body 13CO2 enrichment which was equal to E at the isotopic steady state. During a non-steady state incremental cycle exercise (5 w/min or 10 w/min), NaH13CO3 infusion rate was successfully increased by the action of feedback controller so as to keep E constant.
